Description
Technical field
The present invention relates to a kind of multimode Intelligent motor energy-saving application system based on Internet of Things, especially relate to by computing machine and pass through the GPRS mobile radio networks, Remote Selection frequency conversion or phased pattern are implemented the application system of economize on electricity to motor.
Background technology
Most of threephase asynchronous that adopts in industrial and agricultural production mainly contains two kinds of frequency conversion reduction of speed technology and phase control techniques to the battery saving mode of this type of motor, is called for short variable mode and phased pattern.Variable mode is dynamically to adjust in real time motor speed, thereby reduces motor shaft power, realizes motor power saving.Phased pattern is the size by the detecting real-time motor load, adjust in real time the voltage and current of motor, under the prerequisite that does not change motor speed, guarantee dynamic, the exact matching of motor output torque and loading demand, effectively avoid motor to exert oneself excessive and waste of energy that bring.The variable mode power savings is remarkable, but because needs change motor speed, production efficiency is affected, thereby range of application is restricted.Phased pattern does not change motor speed, does not affect production efficiency, be of wide application, but power savings than variable mode slightly a little less than.
The electricity-saving appliance that designs for threephase asynchronous at present, or adopt the variable mode design, for the occasion that allows speed governing; Adopt the phase control techniques design, for the occasion that does not allow speed governing.Motor is solely adopted frequency conversion or the economize on electricity of phased pattern, just produced the contradiction between production efficiency and the electric energy.
Concrete-agitating industry for example, the roller type band conveyor is for delivery of sandstone.The actual loading situation of roller type band conveyor is divided into 3 kinds of zero load, underloading, heavy duties.From the whole technological process of concrete production, the production efficiency between each production link needs mutually coupling, carries the speed of sandstone in different time sections different demands to be arranged.Pair roller formula band conveyor is implemented single variable mode economize on electricity, can run into very light but the situation that the transporting velocity demand is very high of actual loading, at this moment variable mode economize on electricity has reduced the sandstone transporting velocity because reduce motor speed, has also just affected integral production efficient.Pair roller formula band conveyor is implemented single phased pattern economize on electricity, can run into the actual negative load-carrying but the not high situation of transporting velocity demand, and the at this moment basic performance of phased pattern power savings technical advantage not obvious, that do not reduce motor speed is not out.Single energy-saving mode can make particularly thorny between production efficiency and the electric energy.
But quite a few commercial production occasion along with the working time section is different, can successively occur allowing speed governing or not allowing 2 kinds of operating modes of speed governing, the application of the roller type band conveyor of routine concrete-agitating industry described above.
Therefore, need new motor power saving technology of development, simultaneously integrated frequency conversion and phased two kinds of energy-saving modes, according to the different production requirements of different time sections, intelligence is switched energy-saving mode, solves the contradiction between production efficiency and the electric energy.On the other hand, also need the switching with the motor power saving pattern, be based upon on the basis of Internet of Things application, according to the overall scheduling demand of production procedure, switch the battery saving mode of a plurality of production links, multiple electric motors by wireless Internet of Things real time remote control, realize the systematization economize on electricity.
